YourStructureName(100) = struct('firstfield', [], 'secondfield', []);

And there you have a struct array of 100 elements, each of which has two fields.

how to sort this array on the basis of second field.thank you

[Walter Roberson]

There is no basis for sorting an array based upon empty fields. If the fields are not empty then you need to define how to determine whether one field content sorts before another. For example if YourStructure(317).secondfield = {'Red Rover', 17}, should that sort before or after YourStructure(111).secondfield = [1/1000-3/507i, inf; nan, -5099e42] ?
